The manufacturer of the Dionex Ultimate 3000 XRS UHPLC System, Dionex is Dionex. Refurbished Dionex Ultimate 3000 XRS UHPLC complete with Dionex Ultimate 3000RS pump (5040.0046 HPF-3400RS), Dionex Utlimate 3000 XRS open autosampler (MXY013-03A), peltier thermostat MN03-01, Thermo OAS-3300TXRS 5845.0010, Thermo Scientific MB01-01A controller for autosampler, Dionex Ultimate 3000 SRD-3600 5035.9230, Dionex Ultimate 3000 DAD-3000 diode array detector 5082.0010, Dionex Ultimate 3000 RS column compartment TCC-3000RS 5730.0000. Up to 2mL/min. flow rate supports up to 125 MPa (18250 psi/1250 bar) backpressure for fast and highly resolving column technologies. The Thermo Scientific UltiMate 3000 Open Sampler XRS system is designed for exceptionally high throughput and ultra-high resolution chromatography. As a front end for LC/MS setups, it provides flexibility, excellent peak sharpness and a very large sample capacity. Featuring a high-end quaternary UHPLC solvent delivery module, it delivers faster gradient responses than many binary systems and supports very long, sub-2µm particle size columns for ultra-high resolution experiments in complex or poorly characterized samples.
